Re: [OpenMap Users] OpenMap 4.6 changes [layer no-delete]

Hello,

I too would like to have the ability to mark a layer as being undeletable.
I was going to do this by setting a flag in my layers (which extend the OM
layers) and not using the OM layer management tools.

I haven't had a look at the code but I don't suppose it would be too
difficult to implement the no-delete property. I think the major amount of
work would be in deciding what the GUI tools should do. Do they disable
the delete option when an undeletable layer is selected; do they allow the
delete button to be pressed and generate an error or do they just silently
ignore the request?

I'm going to have to resolve the issue soon'ish so I'm prepared to do some
work on the code if there's a consensus on the way to go.

regards,

Adrian

Hi,

[...SNIP...]

I have a problem in my application. A few layer must not be removed
by user. How to stop user from deleting layer? Doas layer has any
property 'removable' or something? If not I'd like to add such
feature to Layer class and hadle it in LayersPanel. Maybe I should
go another way?

Regards,
Piotr Kaminski
